Setting: ShowLocationInfoInCalledShot (true/false, default true)
When true, structure and armor of hovering location will be displayed in the called shot window.
This information replaces the name of called location. The location name is instead displayed as window title.

Setting: FixBossHeadCalledShotDisplay (true/false, default true)
When true, boss head will be unselectable in called shot.
Before game version 1.3, any attack on an important NPC (which is headshot immune) will remove the head from the global hit table. As a result, no one's head can be hit. All heads will be greyed out in the called shot popup. This was called the grey head disease by some and can only be cured by loading game or using an earlier version of AIM.
This is fixed in patch 1.3, by cloning the hit table in every hit. Slow, but a working fix nonetheless. But this also mean boss head can now be called, when in fact you will never hit the head. This setting fix that.

Setting: MechCalledShotMultiplier (0 to 1024.0, default 0.33)
This setting let you tune called shot's weight multipliers.

Setting: VehicleCalledShotMultiplier (0 to 1024.0, default 0.75)
Unmodified called shot is pretty powerful on vehicles because of its low number of locations. This setting tries to balance that.

Setting: ShowRealMechCalledShotChance (true/false, default true)
Setting: ShowRealVehicleCalledShotChance (true/false, default true)
When true, the popups will reflect modded hit distribution such as clustering and multiplier effect.

Setting: CalledChanceFormatSet to "{0:0.0}%" to always show one decimal, or "{0:0.00}%" for two decimals. Leave empty to round them to nearest integer.
